curl_close($ch); // close cURL handler

echo "The server responded: <br />";
        echo

    }

}

Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

There is a constant missing from that list.  CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

curl_getinfo($ch) will also return 'redirect_url' if there is one (even if CURLOPT_FOLLOWLOCATION set to false).
I don't know why it's not in the doc..

CURLINFO_HTTP_CODE does not return a string, as the docs say, but rather an integer.

<?php
    $c
= curl_init('http://www.example.com/');
    if(
curl_getinfo($c, CURLINFO_HTTP_CODE) === '200') echo "CURLINFO_HTTP_CODE returns a string.";
    if(
curl_getinfo($c, CURLINFO_HTTP_CODE) === 200) echo "CURLINFO_HTTP_CODE returns an integer.";
   
curl_close($c);
?>

returns

"CURLINFO_HTTP_CODE returns an integer."

The main doc neglects to mention that when the CURLINFO_HEADER_OUT option is set the array returned by this function will included a new property, request_header, that is a string of the headers sent in the request.

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:

This doesn't work:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

This works:
<?php
$ch
= curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>
